If you have been thinking about brightening your smile, you have probably already noticed that there is no shortage of options out there. Whitening strips at the drugstore, whitening toothpastes, charcoal powders, and then there are the professional options your dentist offers, including whitening trays teeth whitening and in-office treatments. It can feel a little overwhelming when you are just trying to figure out what actually works.
At Orangewood Family Dental, we get this question from patients all the time. The answer is not one-size-fits-all. The right option depends on your goals, your schedule, your budget, and what is currently going on with your teeth. So let us walk through both options honestly so you can make the decision that works best for you.

What Is In-Office Teeth Whitening?
In-office whitening is done entirely at the dental office in a single visit. Your dentist applies a professional-strength bleaching gel directly to your teeth, and in many cases a special light is used to activate the gel. The entire process usually takes about an hour, and you leave the appointment with noticeably whiter teeth the same day.
This option works well for patients who have an event coming up, such as a wedding, a reunion, or a job interview, and need fast results. It is hard to argue with the convenience of walking in and walking out with a brighter smile in one appointment.
A few things worth knowing about in-office whitening:
- It comes with a higher price tag compared to custom tray teeth whitening
- Some patients experience tooth sensitivity after the procedure
- Results are immediate but may fade faster without any ongoing maintenance
- It requires one dedicated appointment at the dentist in Phoenix AZ
What Are Custom Teeth Whitening Trays?
Custom tray teeth whitening is a dentist-supervised, at-home whitening method and it is actually the approach Dr. Fullenkamp recommends most often to patients at our Phoenix office.
Here is how it works. Your dentist creates custom teeth whitening trays that are made to fit your unique smile. At Orangewood Family Dental, no impressions are needed, which means you can leave the office with your trays that same day. You then use the trays at home by placing a professional whitening gel inside them and wearing them for a set amount of time each day.
The whitening trays teeth whitening gel contains peroxide, which breaks down into hydroxy radicals that lift stains from the enamel. Because the trays are custom fitted, the gel stays exactly where it needs to be, unlike one-size-fits-all strips that can slip around and cause uneven results.
The process typically takes 10 to 14 days from start to finish, although many patients start noticing a difference in as little as three to five days.
